What 5Stack is
5Stack is a self-hosted Counter-Strike 2 competition platform for communities and organizers who want competition tools under their own hosting. It brings together server provisioning, matchmaking, tournaments, statistics, replays, broadcasts, and community moderation. Players can queue for 1v1, 2v2, or 5v5, with regional matching that checks latency and supports parties. Organizers can choose formats such as Single or Double Elimination, Round Robin, and Swiss, as well as multi-stage brackets and seasonal leagues. Match analysis covers economy, clutches, roles, heatmaps, and movement paths. Browser-based 2D and 3D replays, demo playback, and automatic highlight reels are available, though some rendering features need a GPU node. The platform also supports broadcasts with a Stream Deck, scoreboard overlays, a public watch hub, and picture-in-picture. It is free and open source, but users must provide hosting infrastructure; the FAQ calls for a Linux server and domain. In-browser demo playback, live streaming, and highlight and clip rendering require an NVIDIA GPU on a native Linux host.
